I grew my garden in lockstep with my family. We moved in to a vast expanse of grass in 1986 (actually a vast expanse of snow, since it was December). For a while the garden grew with the family—add a child, add a flower bed. Five pregnancies later I had a full garden (although only two children—the goddess was kinder to the yard than to the pregnancies).
As the children grew in complexity so did the garden, adding vegetables, trees, more flowers, patios and a pond. The children are grown and gone and the garden is grown yet comes back every year, a lovely metaphor on the nature of parenting adults.
